Attention: The rack-mounting frame may not be able to support the weight of the
networking switch with only the front post mounting brackets (2-post application). If
the switch has an undesirable amount of sag, it is recommended to use a 4-post
mounting kit.
Attention: For earthquake stability, mount the switch in a 4-post rack.
